Unique lab opal engagement ring or wedding ring featuring a blue topaz set in sterling silver. Each side of this handmade engagement ring is inlaid with 3 pieces of lab grown opal. The lab created opal is a medium blue with flashes of light blue and green. This synthetic opal rivals the colors and fire of the best Australian opal at a more affordable price. The center gemstone is a princess cut paraiba blue topaz. The topaz weighs .75 carats and is securely held in the mounting by 4 corner prongs. The ring measures 7.5mm wide at the top and tapers to 4.5mm at the bottom. This ring would make a great wedding or engagement ring for someone looking for a unique alternative to a traditional diamond. A matching wedding band (style W134) that could be worn with it is also available by special order. The engagement/wedding ring is shown in a size 7 1/2 snug, but will be made to order in your ring size in 4 to 6 weeks. This ring is also available in other opal colors or with other inlay materials and other center stone choices.
